ILI9225 SPI TFT Library for RaspberryPi/OrangePi.
This library can show a chart to ILI9225 SPI TFT.
Wirering
| TFT | Rpi/Opi | |
|---|---|---|
| CS | -- | Pin#24(SPI CE0) |
| RST | -- | Pin#5(*) |
| DC | -- | Pin#3(*) |
| SDA | -- | Pin#19(SPI MOSI) |
| CLK | -- | Pin#23(SPI SCLK) |
| GND | -- | GND |
| 5V | -- | 5V |
(*)
This is default.
If you want to use other pin, You have to change this.
#define D_C 2 // GPIO2(Pin#3)
#define RST 3 // GPIO3(Pin#5)
build with bcm2835 library (very fast)
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.56.tar.gz
tar zxvf bcm2835-1.56.tar.gz
cd bcm2835-1.56
./configure
make
sudo make check
sudo make install
cd $HOME
* This tool require 1.56 or later.
* Because this tool uses bcm2835_spi_write.
